HARRY S. MOORE, OF BRIDGETON, NEW JERSEY, ASSIGNOR OF ONE-HALF TOSTANTON B. COLE, OF SAME PLACE.

MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 504,886, datedSeptember 12, 1893.

Application flled June 22, 1 892.

To aZZ whom it may concern:

Be it known that I, HARRY S. MOORE, a citizen of the United States,residing at Bridgeton, in the county of Cumberland and State of NewJersey, have invented certain new and useful Improvements inMerry-Go-Rounds;

andd do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theartto which it appertains to make and use the same.

My invention consists of an improvement in that class of devices knownas merry-g0- rounds and contains certain novel features of constructionfully shown in the accompanying drawings and described in thespecification following. I r

In the drawings Figure 1 is a perspective view of my improved device.Fig. 2 is a plan view of the gearing. Fig. 3 is a partial sectional viewof the same. Fig. 4 is a detail View of my preferred form of bearing forthe central gear wheel, and Fig. 5 is a sectional View of the ballbearing support for the frame.

One of the principal objects of my invention is to provide a swingingmerry-go-round or one having a swinging and circular movementsimultaneously.

Referring to the drawings in which similar letters of reference indicateidentical parts throughout, A represents the main supporting pole orstandard extending upward from a base to which it is rigidly secured,the top of which is provided with a recess mm which is placed a suitablebearing to receive the lower half of a ball, leaving the upper halfexposed. A cap B is provided and adapted to lit the upper half of saidball. 0 is a ring of metal or other suitable material to whicharerigidly secured the arms D, which may be made jointed if desired soas to occupy the smallest possible space for packing. The outer ends ofthe arms D may be secured together in any desired manner. From the outerextremities of the arms D to the outer edge of the cap piece B areextended supports rom the arms D there are downwardly extending pieces dwhich serve to support the circular base E upon which are placed chairs,wooden horses or other analogous devices to be used Serial No. 437,612.(No model.)

by passengers. structed in such a manner as to permit lateral movementto the frame, its central portion being removed for that purpose. Arailing F may be placed if desired upon the outer edge of this circularbase E for the purpose of increasing the safety of the passengers. Uponthe supporting pole A at a point between the circular base E and thering 0, is revolubly mounted a large gear wheel G. To the upper side ofthis gear wheel G are attached brackets g at opposite points. In theouter end of this bracket is pivoted the pin g having a divided head orupper end; a like pin g is pivoted in two of the arms D. A link hispivoted in the'upper ends of the pins 9, g so that the motion given tothe gear wheel G is communicated to the frame of the machine and theseats or horses carried thereby. This connection while providing for theproper revolution of the main frame admits of any lateral movement whichmay be communicated thereto. Motion is imparted to the gear wheel G bythe spur gear H on a vertical shaft H provided with a beveled gear wheelat its lower extremity which meshes with a second beveled gear wheelmounted on a horizontal rod to which power is applied. Any form ofgearing may however be used, and any mode of applying power, as thesedevices form no part of my invention. Above the gear wheel G upon thepole A there is revolubly mounted as shown in Fig. 4:, a cog wheel I. InFig. 4 of the drawings, I have shown a'collar interposed between thewheels G and I. This collar may be loose and perform the function ofasimple washer or it may be rigidly secured upon the standard andsupport the wheel I. Above the wheel I a bracket I is rigidly secured tothe standard. I prefer to form the bracket integral with and projectingfrom a collar surrounding the standard, but it may be secured to thestandard in any other way. In order to secure the wheel I to thestandard and hold it stationary,

The circular base E is con- I a pin '6 movable in an opening in thebracket IOO in a groove in the standard within the wheels G and I asshown in the drawings. Thelower end of the shank may be pivoted to alever,

said lever extending outwardly to some point easy of access. The pin maybe manipulated in any manner however. Meshing with the wheel I andmounted upon the wheel G as shown, on opposite sides thereof, are cogwheelsI' 1. Similar cog wheels I Pare mounted in the same manner on thewheel G near its rim and gear with the wheels I I. To each of the gearwheels 1 1 is rigidly secured a crank arm K K, having pivoted to them ornear their outer extremities, rods or their equivalentsL L which arepivotall y connected to two opposite arms D D of the frame of themachine.

In my preferred construction shown in Fig. 2, a spring is interposed atthe point of connection of the rods L with the arms D to avoid anyjarwhich might otherwise occur. It. is obvious that the spring may belocated with equally as good effect at the point where the rodLconnectswith the crank arm K. Y

In Fig. 2, the wheels I are shownasbeing smaller than the wheel I. Thiswill give the swinging movement at intervals, less than one entirerevolution of the wheel- G and the frame. I prefer however, to formthewheels 1 =of the same size as the wheels I and produce the swingingmotion at opposite sides of the machine, or a to and fro motion .at eachentire revolution of the wheel G.

The-mode of operation of my improved machine is obvious. Power beingapplied the. gear wheel H is set in motion which meshing with the largewheel G rotates the frame of the machine upon the ball bearing win therecess at the top of the pole A and upon which bearing the entire frameis supported. As soon as themachine hasacquired sufficient momentum inits circular motion, the pin i is depressed and made to engage theopening in the wheelI and forces the cog wheel Ito remain stationary.The stopping of the wheel I and the continued motion of the wheel G,sets in motion the gear wheels I I, I 1 and consequently the crank armsK K which being secured to themain frame of the machine by theintermediate arms L L give the machine a lateral motion at certainpoints in its rotation, thus making the frame and base swingsimultaneously. The ring 0 is made of sufficient diameter to permit theswinging movement to equal the length of the crank arms K K, and the capBis mounted on its bearing in such a manner as shown in the drawings aswill permit rotary movement in anydirection.

In using the machine as an ordinary merrygo-round the cog wheels G and Irotate to gether, and in order to insure their unity of rotation,I-provide a pin is bent at right augles as shown, the horizontal portionof which projects from a collar M mounted loosely upon the standard, andadapted to be engaged by the lugs i i provided on the .pin 1'. By thisarrangement it will be observed that by raising the pin 1; the verticalpart of the pin 70 will be thrust through suitable openings in thewheels G and I and the part '5 of the pin 11 be forced out of connectionwith the wheel I when thewheels G and I will rotate together. Bylowering the pin 2' the part k of the pin 70 will be forced out ofengagement with the wheel I and the part i of the pin 11 into engagementwith said wheel, holding it in rigid connection with the standard.
